FOQ of liquid RTV2 silicone rubber artificial stone mould making :
Why does the RTV liquid silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products
Characteristics of liquid RTV2 silicone rubber artificial stone mould making
1. Good flow ability and long working time
2. Medium hardness stone mold making
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage
Applications of liquid RTV2 silicone rubber artificial stone mould making
RTV2 Silicone rubber series are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.
RTV-2088 silicone rubber is a kind of silicone which is especially suitable for the reproduction of artificial stone,cement stone,concrete stone and manufactured stone moldmaking.
Storage of liquid RTV2 silicone rubber artificial stone mould making
When the RTV2 Silicone Rubber is stored at or belo liquid RTV2 silicone rubber artificial stone mould making w 30 C (85F) in the original unopened containers, Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production.
